ADDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 344,025, dated June 22, 1886.

Application filed June 8, 1885.

To all whom it may concern:

Be it known that we, BnowN M. BARNES and CHARLES E. SHAPLEYpf Dryden,county of Tompkins, State of New York, have invented certain new and useful Improvements in Adding-Machines, of which the following is a full and exact description, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is aperspeetive view of the device complete. Fig. 2 is a face View, partly in sec tion, showing the means for transmitting motion from the units and tens disk to the hundreds and thousands disk. Fig. 3 is a perspective view of the cover, taken from the inner side. Fig. 4 is a partial sectional view showing the spring for holding the hundreds and thousands disk in engagement with its operating-pinion,and also the device for throwing the same out of engagement therewith, in full and dotted lines.

Fig. 7 is a view of a portion of the bottom of the case, showing the slot or opening through which access is obtained to move the hundreds and thousands disk by hand. Fig. 8 is a perspective view of the device,with a portion broken away to show the pawl for operating the units and tens disk. Fig. 9 is a face view of the same, also partly broken away. Fig. 10 is arear view,showing the slot therein and the perforations in the hundreds and thousands disk by which the same is set.

Our invention relates to that class of instruments,known as adding-machines, employing two or more peripherally-numbered disks, the first denoting units and tens and the second hundreds and thousands, and in which a complete revolution of the first disk, through suitable mechanism, is made to move the second disk one point to denote the hundreds; and our invention consists in a novel construction of disks; in a novel means for communicating motion from the units and tens disk to the hundreds and thousands disk; in a novel Serial No. 108,003.

(No model.)

device for locking and releasing the hundreds and thousands disk at each complete revolution of the units and tens disk; in a novel means forholding the hundreds and thousands disk in engagement with its operating-pinion, and the combination therewith of means for throwing said disk out of engagement with its operating-pinion; in a novel means for setting the disks, and to certain details in the construction and arrangement of parts, all as here inafter explained.

The case A, in which the disks and their operating mechanism are mounted, is preferably made in cylindrical form, and may be formed by having the rim or flange A connected to the head or bottom A, as shown, or by having said rim or flange stamped or formed in a single piece with said head, and is provided with a suitable cap or cover, A, havin g inscribed upon its face,near its outer edge, a series of lines radiating from the center,and with suitable figures opposite said lines from O to 99, as hereinafter referred to.

The units and tens disk B is provided with a rim or fiange, 1), formed thereon by being either stamped up in forming the disk or by being spun thereon, and upon the periphery of which flange is suitably inscribed or marked the figures from O 0 to 99. This disk is also provided near its outer edge adjacent to the rim with squared or elongated perforations 1), arranged opposite and corresponding to the figures upon the periphery of the rim or flange, and which perforations extend entirely around the circle of the disk, their side faces being preferably cut on lines radiating from the center of the disk, the dividingavalls between said perforations forming teeth with which the actuating-pawl, hereinafter referred to, engages for moving or revolving said disk. This units and tens disk is further provided with a single perforation, 1)", outside of and between the circle of perforations b and the rim, and at such a point as to engage the actuating-pinion 0 of the hundreds and thousands disk at each complete revolution of the units and tens disk. The disk is cut from points near the upper and lower edges of this perforation If in such manner as to form a spring or yielding tongue, If, at one side of said perforation, to permit the tooth of the pinion C, after being engaged by the perforation, to actuate the same to escape therefrom.

The hundreds and thousands disk B" is constructed in a similar manner to the units and tensdisk, having a series of perforations, but which perforations are formed on a circle corresponding to the distance from the center that the single perforation b is cut in the units and tens disk, and with which perfora-- frame of the bearings O in such manner as to.

engage the teeth of the pinion to hold the same from turning, said dog being actuated or moved out of engagement with the pinion at each complete revolution of the units and tens disk by means of a pin or stud, D, projecting from the inner face of said unit and tens disk, and arranged in such position thereon as to throw said dog out of engagement just as the pinion is engaged by the perforation I)".

The bearing for the pinion, as before stated,

is shown as suspended from the rim of the case, as this construction has been found they most desirable in practice; but, if desired,

however, the bearings may be connected to. the center shaft, or arranged in any preferred 1 way, the actuating tooth or perforation N, as also the perforations in the hundreds and thousands disk, being cut in the disks to correspond thereto.

The hundreds and thousands disk is mounted in the case upon a short shaft, E, secured to the bottom of the casing, with its projecting rim toward the bottom of the case, being held from outward displacement by means of guide pins or lugs E", secured to the rim of the case in any preferred way, and being held closely engaged therewith by means of a flat spring, F, secured to the bottom of the case, and arranged thereon at a point near to the operating-pinion to hold the disk in engagement therewith. These pins alsoserve as a support for the units and tensdisk, and also hold the two disks apart, or in proper relation to each other. A pin or projeetiomf, is secured to the inner face of the hundreds and thousands disk, at such a point thereon as to engage the spring F in the revolving movement of the disk, and which pin, in connection with the spring, serves the double purpose of giving an alarm,when the hundreds and thousands disk has made a complete revolution, by the dropping of the spring from 011' the pin, and as a means for setting said disk when the same is moved backward by hand, by the pin coming in contact with the free end of the spring, at which point the 0 0 on the rim of the disk are exactly opposite the aperture in the rim of the casing, and in position to be started in the forward direction. A shipping-latch, G, is pivoted to the case at a point slightly in advance of the operating-pinion (l, and projects into the case through an openingformed in the rim thereof, said projecting end being curved in such manner that when the thumb end of the latch is raised the inner end will engage the face of the disk 13 and force the same backward, overcoming the tension of the spring F, and throw the disk out of engagement with its operatingpinion, permitting said disk to be turned by hand. To permit this resetting of the disk by hand, the head or bottom of the case A is slotted, or provided with an opening, H, and the disk B is provided with a series of openings, H, arranged in a circle at such distance from the center as to come opposite the opening H, by which arrangement it will be readily seen that when the disk is disengaged from its operating-pinion by means of the latch, by inserting the finger, a pencil,or other suitable device through the opening H into any one of the openings H the disk can be turned so as to bring the 0 0 opposite the opening in the case, as before stated.

The units and tens disk is placed in the case with the rim thereon projecting outward, so

that the flat surfaces of the disks shall be adjacent to each other,which permits the device to be brought into more compact shape.

The hand or pointer I is secured by means of a screw, 1 to a short shaft, 1, which projects through the case. This shaft has also rigidlysecured to it upon the inner side adjacent to the cover an arm, L, which carries upon its outer end a spring-pawl, L, which engages the perforations b in the units and tens disk'to revolve the same.

As the pointer and arm which carries the pawl are both rigidly secured to the shaft, it will be readily seen that when the pointer is moved from the starting-point on the face of the cap or cover any number of points the units and tens disk will be carried by the spring-pawl forward an equal distance or number of points and register a corresponding number through the opening in the rim of the case. The shaft I also serves as the bearing or pivot on which the units and tens disk ICO revolves. A spiral spring, M, is mounted on V the shaft I, and serves to'hold the units and tens disk in proper position and against the operating-pinion of the hundreds and thousands disk with ayielding pressure. A springstop, N, is secured to the inner side of the cap or cover, which is provided with a thumbpiece, a, which projects out through an open-' ing in said cap. A pin, N, is secured to the rim of the units and tens disk B at a suitable distance from the starting-point,said stop and pin being used in setting the units and tens disk, which is accomplished by pressing the stop inward by means of the thumb-piece and turning the pointer from right to left until the pin N engages with the stop N, which will bring the cipher on the disk opposite the aperture in the casing, when, by returning the pointer to the stop on the face, or opposite the cipher thereon, the machine will be ready for operation.

The operation is as follows: After the machine is set with the ciphers on both disks opposite the apertures in the rim of the easing and the pointer against the stop on the cap or dial plate, by moving said pointer forward to any figure on the dial a corresponding number will be exhibited through the apertures in the case. hen the units and tens disk has nearly completed one revolution, or registered between and points,the pin or stud D on said disk will commence to engage the spring locking-dog D and to force the same out of engagement with the operating-pinion, and in the continued forward movement of said disk, and just as the number 99 is'rcgistered, the locking-dog will be thrown entirely out of engagement, at which point the perforation b will engage the pinion, which having been released momentarily is carried or turned by the continued forward movement of the units and tens disk sufficiently to move the hundreds and thousands disk one point, at which time the pin or stud D is disengaged from the locking dog, which immediately re-engages the pinion and looks it and the hundreds and thousands disk until the units and tens disk has made another complete revolution, when the operation is repeated.

From the foregoing description it will be seen that the hundreds and thousands disk is operated positively through the units and tens disk once at each revolution thereof, and is locked securclyin place during the other portion of the movement.

\Ve do not wish to limit ourselves to the particular construction and arrangement of parts shown and described, as it will be readily seen that various modifications maybe made therein without departing from the spirit or intent of our invention.

Having now described our invention, we claim- 1. The combination of theperipherally-numbered revolving disk, having the circle of openings cut therein corresponding to the numbers on the rim or flange, a cover for the case in which the disk is mounted, having the radial lines and numbers marked thereon corresponding to the numbers on the disk, a pointer or index-finger to move over the outer face of the cover, and a spring-pawl having a fixed relation to the pointer, arranged within the case to engage the circle of openings as the pointer is moved in one direction, and to ride over the same when moved in the opposite direction, substantially as and for the purpose set forth.

2. A disk provided with a circle of openings, and a single opening outside of the circle of openings, the pointer provided with an actuating-pawl to engage said circle of openings and to operate the disk, in combination with a second disk provided with a circle or series of openings, and a pinion in engagement with the second disk, and adapted to engage the single opening in the first disk at each revolution of the same, substantially as and for the purpose set forth.
